Checking in and checking bags for flights

Southwest; I learned when I first started flight them; check in 24 hours early to get into thet A group. Most of the time this works;

Checking in my bags; I use skycab! They are nice and have people skills. I always provide a $2.00 tip per bag.
I believe it is worth  to use the skycab;
1) the line is shorter
2) they are nicer workers
3) the process moves and I am a happy camper not unhappy based on customer service.
4) my bag has never been lost for good
5) you do not pay for bags

Other airlines; I have learned to check-in 24 hours early.  These check-ins also provide you the opportunity to print a boarding pass.

Other airlines; I try to use the skycab; however, since on a budget and being at airports very early; I do not mind waiting in line at those airports inside to check my bags. Also; these airlines cost $20.00-$25.00 per bag to check them in. Therefore; I do not want to pay another fee as a tip too. However; this is the best option; one less item not to track while in the airport traveling from location to location.
